When Alice was touch typing on her QWERTY keyboard (Figure 1), she accidentally shifted both of her hands rightwards by one key, so
e, etc. (
[). Spaces were not affected because the space bar was quite big.
Your task is to help her fix her message using the shortest number of bytes, i.e. undo the shifting of her hand positions. More precisely, you will be given a string consisting of spaces as well as characters from
wertyuiop[sdfghjkl;xcvbnm, and you need to map the characters to
qwertyuiopasdfghjklzxcvbnm and leave spaces untouched.
Here are some testcases for you to test your program:
input output ---------------------- s[[;r apple s gom a fin werty qwert uiop[ yuiop sdfgh asdfg jkl; hjkl xcvb zxcv nm, bnm ;p;;o[p[ lollipop [2 spaces] [2 spaces]
lollipop testcase starts with a space)
Figure 1: Alice's QWERTY keyboard
This is code-golf. Shortest answer in bytes wins.
